According to a report from Ling et
al. In 1990, that more than 90% of sea turtle populations in China are
distributed in the South China Sea. However, the political instability
in the region complicates the sea turtle survey and conservation measures.
The marines from the nations in the region occupy most of the islands.
Very little information is known about the nesting and feeding populations
of sea turtles. With the collaboration of Council of Agriculture and Defense
Department, two surveys were carried out in July 1994 to Pratas Island
and in April 1995 to Taipin Dao of Spartly Islands. The 12-days survey
on Pratas Island found very few nesting hawksbill turtles and no green
turtle nested on the island. The nesting season occurs in the summertime.
A recent reef check on Pratas Atolls in 1998 revealed severe reef bleaching
in the lagoon region. All the evidences suggested substantial destructive
fishing using KCN solution and dynamite in this region.
A 5-days survey on Taipin Tao showed
that both hawksbill and green turtles could be found nesting on this island.
There are, however, more nesting green turtles than the hawksbill turtles.
Questionnaire interviews showed that the nesting green turtle population
is between 25 to 35 females annually and the nesting season lasts all-year
round. The nesting environment in the adjacent islands is severely destructive
by the Marines from other nations. Pirates and illegal fishing are among
other serious problems in this area.
Both surveys showed that the protection
of nesting beaches on these islands are insufficient to conserve the sea
turtle populations in the South China Sea. It is strongly recommended that
ASEAN should expand their sea turtle conservation program to include all
nations who deploy Marines to occupy islands in the South China Sea, and
all governments work cooperatively to save our declining sea turtle populations. |
